In this case, the flexible circuit board 700 connected to the display panel 400 is bent toward the first bottom part 610 along one sidewall of the storage container 600, and as a result, a printed circuit connected to the flexible circuit board 700. The substrate 500 is disposed on the first bottom portion 610 of the storage container 600.

Subsequently, the first and second accommodating parts 621 and 626 formed on the first bottom part 610 accommodate the first and second side surfaces 510 and 520 of the printed circuit board 250, respectively. The substrate 500 is fixed to a predetermined position of the first bottom part 610 to complete the assembly of the display device 20.

According to the display device described above, since the screw is not used to fix the printed circuit board, the number of screw fastening process steps is reduced in the assembly process steps of the printed circuit board of the display device, thereby improving the productivity of the assembly process of the display device. .

As described in detail above, according to the present invention, a housing is disposed on the bottom of the storage container and includes a first storage part and a second storage part without using screws to accommodate the circuit board in the storage container. The circuit board is accommodated in the storage container by this.

Therefore, in the assembling process steps of the display device, the number of screw fastening processes is reduced, thereby reducing the assembly work time and providing a display device that can be easily assembled.

In the detailed description of the present invention described above with reference to the preferred embodiments of the present invention, those skilled in the art or those skilled in the art having ordinary skill in the art will be described in the claims to be described later It will be understood that various modifications and variations can be made in the present invention without departing from the scope of the present invention.
